I can't remember if you are a 1.6 or 1.8, but stroke is 83.6 and 85mm respectively. Rod length for both engines is 132.9mm. In comparison the f20c has a bore of 84mm and rod length of 153mm. So why does the f20 rev so eagerly while the B engine falls on its face? IMO the head, the B is a very old design while the f20 is a much newer platform, aided by the time honda spent in both F1, IRL, and motorcycles.

The little b engine is hamstrung with poor flow characteristics, which will always be the limiting factor in high redline number...sure you might be able to twist it up there, but you are not gaining anything performance wise. Proof is in your plot.

Who cares about max redline anyway? All that matters is your car rocks hard when you push on the fun pedal!!

AWESOME JOB!!
No argument here! Just took a few buddies for a quick spin during lunch, lots of swear words...haha

Lets see your timing map!

you can probably advance some on the top end and grab some more of that torque loss back.

Or, you can have me make you an intake manifold and then do both.

I've been eying your manifolds, we might be talking this winter

Picture blast, get ready! Got the photos up from the Larz Anderson meet last Sunday! My buddy has the blue DA. Hope you enjoy!

reving past stock redline is pointless until you 1. get a new IM, or 2. get a .86 housing.

We stopped and did a mini shoot on the way home as well.

That right there is a diff!

No those aren't Rotas












A wet sand is next on the list, I know








Enjoy!

The 7th photo kinda looks like a slightly chubby girl muffin-topping her (not so) skinny jeans.

I'm not sold on the wheels, but other than that, it looks pretty clean.

haha. It's cool man.

Some other slight notes about the car, I finally put on all the JDM badges, as can be seen in the previous pics. I also sourced 24 of the "short" acorn bolts (there were 2 on the front of the valve cover on 90-93 cars), and replaced every bolt I could in the engine bay with them. I've slowly been replacing the nuts with acorn ones (shock towers, master cyl, clutch master cyl, etc). Small detail, but one I'm proud of.

whoops missed your post. I might revist an intake manifold over the winter, but for now, it's "finished". About the torque curve, it is what it is.

Another question for all you smart guys, would messing with the cam gears be worth it? We didn't mess with them on the dyno.

Also, how do I even post the timing map?

Cam gears for cam timing? YES. Try to find a post where cam gears were not beneficial for tuning normally aspirated cams for boost. And especially at your boost. Cheap power IMO.

Try a screen dump for your timing map.

Do you have larger versions/images of your car online? I wanted to see some detail in your engine bay.

Ok, I'll add it to the list of things to do when I get bored with the power I have now. I'll try and post the timing map tonight. All the pictures I currently have I've posted- what are you looking for in particular? I can take some for you.

Just your engine bay. My car has a color change- red to dark silver metal. So the engine bay will go to a dark machine gray while the engine is out. Just want to figure out what I'm up for since I know you went all out.

I never posted a pic of this, but I converted all the interior lights to LEDs. I did the entire cluster, including all the indicator lights, blinkers, high beams, etc, as well as the HVAC and footwell lights.

blinkers on


blinkers off


HVAC cluster

Sick.
I have been thinking about doing this / custom gauge layout as well. Any good sources for components for this project or just here and there?

superbrightleds.com for all the bulbs.

revlimiter over on clubroadster makes gauge faces (I actually have been going back and forth with him designing a set for my car too)

Looks like my set except I went red. Got my bulbs from them also, great vendor.
